Well, I believe you. I just tried to do the opposite. I selected VASM > Hardware > mouseand selected a two button mouse trying to make my scroll not work.I thought maybe I had to restart the x-server to get the new setting to take effect, but no matter what I did the scroll always worked. So maybe we should try something else as the the advice I first gave does not seem to work.

Could you post your xorg.conf line for your ServerLayout and mouse. Go to /etc/X11/ then open xorg.conf with mousepad.

Also, did you set-up so that you can launch into the text user interface from your boot screen?If so maybe I can take you through some VASM utilities while the x-server is not running.If not I'll just have to get you to set up to launch into text mode.

I tried with and without commenting the last line (ZaxisMapping), but it didn't work.

After any change, I logout and restart xserver to see if the changes have come into place, but I've not had much luck!

I have set up Vector Linux such that I always start into text mode and need to manually start xserver (with a 'startx') to get it working. I prefer working in the command line and use the x to view pdfs (images) and check mail (not familiar with mail clients).

However, a scroll not working can be a major pain! Thanks for all the patience and the help.

Thanks a lot! The scroll is working now. In fact, the required line is present, but has been commented out. I uncommented it and restarted x, and everything works exactly the way I want it!

@ bigpaws :

I had tried uncommenting that line but I never had any success. But, out of curiosity, what does ZAxisMapping erally do? A lot of sites gave that as the solution, did not understand exactly what it does.
